RICE QUALITY AND PROCESSING Low - Temperature , Low - Relative Humidity Drying of Rough Rice
نویسنده
چکیده
The use of low air temperatures (79 to 93 °F) and relative humidities (19% to 68%) to dry thin-layer samples of rough rice to the desired 12.5% moisture content was investigated. Drying rates and durations and their effects on the quality parameters of head rice yield, color, and pasting viscosity of longand medium-grain rice cultivars harvested at 19.6% and 17.5% moisture contents, respectively, were determined. Results showed that dehumidification of the drying air had greater potential for increasing drying rates at 79 °F than at 86 °F and 93 °F. Low drying air temperatures and relative humidities had no adverse effects on head rice yield or color compared to controls. Peak and final viscosities of low-temperature and low-relative humidity dried samples were similar to controls.

Properties of Flours and Starches as Affected by Rough Rice Drying Regime
Cereal Chem. 80(1):30–34 Flours and starches from rough rice dried using different treatment combinations of air temperature (T) and relative humidity (RH) were studied to better understand the effect of drying regime on rice functionality. Rough rice from cultivars Bengal and Cypress were dried to a moisture content of 12% by three drying regimes: low temperature (T 20°C, RH 50%), medium tempe...

The effects of hot air temperature (40, 50 and 60 oC) and Radiation Intensity (RI) (0.21, 0.31 and 0.41 w/cm2) on the response variables (drying time, Head Parboiled Rice Yield (HPRY), color value and hardness)) of parboiled rice were investigated. The drying was performed using hybrid hot air–infrared drying. The optimization of drying variables and the relationship b...

Two long-grain rice cultivars/hybrids (‘Wells’ and ‘CL 161’) harvested from locations in Arkansas were used in this study. Rice samples were milled for 20, 30, 40, and 50 seconds. Milled whole-rice samples were cooked in excess water for 16, 18, 20, and 22 minutes and in a 2:1 water-to-rice ratio for 20 minutes (WR20). Cooked rice texture and solid leach were determined. Results indicated that ...
